This was a device that I put together for burning pans. At that time I (mistakenly) believed it was important to get the drum red hot. The "barrel" at right has an industrial extractor fan attached, which forced air into thr larger drum which had a kind of grill arrangement on which the fire was lit. The pan sat on two iron bars above the fire. It took about 3 minutes to get the whole pan glowing red. The fan was originally used on the ICL 1301 installed and maintained at Rhodes University by my Dad in about 1966.
